Heat accumulating type microwave heat treatment equipment and organic volatile gas treatment system

Abstract

The invention provides heat accumulating type microwave heat treatment equipment. The heat accumulating type microwave heat treatment equipment and volatile organic compound gas input equipment jointly form an organic volatile gas treatment system. The heat accumulating type microwave heat treatment equipment is composed of a microwave heating module, an air inlet module, a heat accumulating module and a heat exchange module. Particularly, in the whole process of performing thermal oxidation treatment on VOCs gas by using the heat accumulating type microwave heat treatment equipment, any openfire is not required to be used, meanwhile, the heat accumulating module and the heat exchange module are used in cooperation, so that switching of an on-off valve is not needed in the whole VOCs gasthermal oxidation treatment process, and safe and stable operation of the organic volatile gas treatment system is improved.

Description

Technical field: [0001] The invention relates to the technical field of organic volatile gas treatment, in particular to a regenerative microwave heat treatment equipment and an organic volatile gas treatment system equipped with the regenerative microwave heat treatment equipment. Background technique: [0002] Volatile Organic Compounds (Volatile Organic Compounds, VOCs) is a general term for organic chemical substances with high vapor pressure and easy evaporation at normal temperature and pressure, but does not include methane, carbon monoxide, carbon dioxide, carbon disulfide, carbonic acid, carbonates , ammonium carbonate, cyanide or thiocyanide and other compounds. It is known that the main components of volatile organic compounds are alkanes (Alkane), low-boiling aromatic hydrocarbons (Aromatic hydrocarbons) and / or halogenated hydrocarbons (Halogenated hydrocarbons), and these organic compounds are used in printing, coating, paint and other industries Organic solven...

Problems solved by technology

[0007] (1) When switching the flow direction of volatile organic compound gas and high-temperature air flow, if the concentration of volatile organic compound gas in each pipeline is not accurately monitored, the phenomenon of volatile organic compound gas backwashing may occur, and severe cases may cause The thermal storage incineration module 41' exploded;

[0008] (2) The regenerative incineration module 41' of the regenerative incinerator 4' includes a first regenerative bed 411', a combustion chamber 412' and a second regenerative bed 413', resulting in the regenerative incinerator 4' The overall volume is too large, thus limiting the application of the regenerative incinerator 4'; and

[0009] (3) the overall construction cost of known regenerative incinerator 4 ' is very high
